58 1. Radio Comfort Digisystem relies on radio technology to transfer the sound between transmitters and receivers. Like all radio systems, it communicates on specific channels. If you use two transmitters on the same channel, or neighbouring ones, there may be interference. Other electronic equipment can also interfere with radio transmissions. Channel planning To achieve optimal radio performance you need to take into account the distance between transmitters and their frequencies. A longer distance between transmitters allows you to use frequencies that are closer together. If several transmitting frequencies are being used in the same room, the frequency differences between the units should be at least 1 MHz for optimal operation. Radio range The radio range between the units is around 30 m (100 ft). However, this may vary depending on the particular environment you are in. 59

59

60 2. Battery maintenance This product has a built in Lithium-Ion Polymer battery. Lithium-Ion batteries do not suffer from so called memory effects and do not need to be routinely discharged to preserve performance. The battery's capacity will degrade over time. This is normal for all rechargeable batteries. Battery lifetime is dependent on usage patterns. The battery is preferably charged little and often; it will reach 90% of its capacity after half its charging time. If stored for long periods of time, the battery is best left semi-charged. Contact your point of purchase when it is time to change the battery. Operating times vary depending on which features are used. 61
